The weather forecasts that you can monitor here are direct result of the ALADIN forecast model
and may vary from the official forecast, which are daily generated by the weather forecaster who uses about
fifty different model results and his experience. Also they may vary from
7-day forecasts of the ECMWF model.

Some of the causes of the difference between direct model output of the ALADIN and ECMWF are:
- ALADIN is regional model and ECMWF is global
- model grid points which are used to generate weather symbol differ both in position and spatial density
- weather symbols in the 7-days ECMWF forecast represent forecast for the whole day and in the 3-day ALADIN forecast represent parts of the day

Weather symbols of ALADIN forecasts are determined from the 3-hour forecasts of: cloudiness and precipitation,
relative humidity and the value of CAPE index of instability of atmosphere, and the wind speed and direction.
Appearance of rain, snow, fog, or thunder, and wind, does not mean that these phenomena will be present during the
entire prognostic period, but at least at one part of it

The highest and lowest air temperature are also a direct result of the model, without amendments of the forecaster.

During daylight saving time weather symbol and wind, as well as the lowest and highest temperatures for the
the morning and forenoon are calculated from 03, 06 i 09 UTC, for the afternoon and evening from 12, 15 i 18 UTC,
and for the night from 21, 00 i 03 UTC.

During normal (winter) computing of time weather symbol and wind, as well as the lowest and highest temperatures
for the the morning and forenoon are calculated from 06, 09 i 12 UTC, for the afternoon and evening from 12, 15 i 18 UTC,
and for the night from 21, 00 i 03 UTC.

As in the case of the 7-day forecast, the ALADIN weather symbols, wind and temperature should also be understood as
one of the announcement of weather conditions in a particular part of the day at one place, but not as the official
weather forecast.
